My DVD player is plugged in to the wall receptacle, however there is no power to the unit. I took it apart and see nothing wrong with the circuit boards. The fuses are good and there are no burned components. So I suspect a bad transformer coil or something of that nature. Any ideas on where I can obtain replacement parts? Or at least how to check these? Any help would be appreciated. Thank you.
Thank you for the concern however I do have over 25 yrs experience with electronics and even formal training in the tv repair field. I guess i was just hoping for a "quick fix" or atleast find someone that has had the same issue with the same model. thanx n e ways.

25 years of experience should help one get out the old multimeter and measure voltages. Suspicion does not help :) Here we have a saying 'meten is weten, gissen is missen' 'to measure is to know, to guess is to miss'
Most of the dvd player have a switching power supply so you could start from the power switch and see if the ps board get's mains power, from there on move on down to checking voltages at the output (red/yellow/black/white wires running to cpu board and dvd player).
Use the guide at: http://www.repairfaq.org/sam/smpsfaq.htm for more info.
Ok 2 things i would suggest here ... 1. Try another appliance ( that is currently working ) thus eliminating the chance of a faulty power outlet.
2. Secondly, depending on the brand name .. some newer units seem to have a life span of 1 - 5 years, 5 if it was operated in the right conditions ( ie: not damp or dusty ) and considerably less if the unit was operated by children with curious or sticky fingers.
Now presuming the unit isn't brand new ( or you would have simply returned it for a warranty claim ) the next best option here is to consider that DVD players are quite cheap and inexpensive. Ok so granted this is neither a solution nor a quick fix to your problem, but i trust you will consider keeping your fingers off the circuit board and away from the power supply for your own safety. Some larger components (ie: capacitor ) store large amounts of power and touching them with a metal object may allow them to discharge to earth ... via whatever it is you may have in your hand at the time. My advice, leave the cover on and take the unit to a repair shop for a quote.
No problem there "El Capitano" in my experience with most appliances, if you don't know anything .. don't fiddle around inside with the cover off, seen too many novice repair jobs go horribly wrong ... and the whole show goes up in smoke, thus eliminating the problem and the finger in the juice now has a smoldering red welt from a massive discharge.
In your case, with 25 years, i'll let you off based on the fact that you are perhaps a quantum leap ahead of most people who like to stick fingers in circuits and power supplies :) No problem there "El Capitano" in my experience with most appliances, if you don't know anything .. don't fiddle around inside with the cover off, seen too many novice repair jobs go horribly wrong ... and the whole show goes up in smoke, thus eliminating the problem and the finger in the juice now has a smoldering red welt from a massive discharge.

If the TV AND the DVD player are not powering on, then it sounds like the problem is at the receptacle or power strip, where the TV and the DVD player are plugged in. Make sure the receptacle or power strip is working. Plug something else in, a lamp, a radio, anything, and see if it works. If it doesn't then the power strip is off or not working or the wall receptacle is not working.
It could need replacing or the outlet that the unit is plugged into is at fault. Check you main circuit breaker panel, to see if a breaker has been tripped. Also, check the outlet's receptacle for internal damage or a loose or broken wire. In addition, try plugging it into another receptacle that is on a different circuit, than the one it's plugged into now. All these things are part of the process of elimination, in troubleshooting and finding the problem.
You have a power supply problem, if the cord is detachable from the player make sure it is snug tight, next pull the cover off and follow the cord to the power supply board to see if the fuse is blown, the other thing I come across is a bad capacitor near power transistor but this will require some technical know how. One final thought, check your unit on another wall receptacle.
Shut down power, unplug from wall power socket, wait a few minutes then plug in and try again. This is the reset process, to load codes into drams properly when the machine is no longer in standby mode.
The problem seems to be that the video out from the kenwood head unit is either faulty or the leads from the head unit to the monitors are faulty. Have you checked to see that the head unit when playing a DVD is set on ZONE 2 so that it transfers the video signal to the headrest monitors?
I have the same exact model and problem. MY sister has the same
model so I tried troubleshooting with her equipment to figure what
exactly was malfuntioning and it is the player itself that does not
work. Nothing is wrong with my cords or screens but when they are
hooked to my player nothing happens. I tried to find just the
player to replace it and I can't. hope this helps.
Good Luck!
This is what LG customer service will instruct you to do. I have a LG LDA-511:
1. Unplug your unit.
2. After unplugging, wait a few seconds then press and hold the power button (yes, while the unit is unplugged). This resets the unit.
3. Plug in your unit.
4. Press the eject button.
If the disc does not come out, then you need service from an authorized service representative.
Found out what my problem was - 2 DVDs were in the unit - need to take unit out of car (very easy - 5 mounting screws, 2 plug in power connections), remove some brackets from within the unit to get to the DVD itself and then just pull the DVD out - took me less than 1 hour - and I am not tech savvy or mechanically inclined by any means
